LOOSE-LEAF-BINDER BOOK.

. Application led February 11, 1922.

To all whom z'tmay concern.'

Be it known that l, LEE KINGSLEY, of Syracuse, in the county of Onondaga, in the State. of New York, have invented new and useful improvements in a Loose-Leaf- Binder Book, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a loose leaf binder book for filing any loose leaf data which it may be desired to preserve and involves the use of a plurality of series of leaves bound together in book form to fold in reverse directions.

The main object is to provide simple, economical and efficient means for binding the several series together in such manner that they will fold flatwise one upon the other or in other words to enable them to lie flat throughout their areas when folded in either direction. Y

Another object is to enable all of the leaves of each series to be attached to 'a single binding strip to constitute what may be termed a multiple sheet unit.

A furtherV object is to assemble the binding strips of the several units to be adhesively secured in relatively thin compact relation to one and the same back piece so that the latter may tie several units together.

A still further object is to adhesively apply the back binding strips to the central portion of a flexible cover of paper or equivalent cheap material and to provide means whereby the entire assembly may be detachably bound to and between stiffer covers which may be more or less elaborate in quality or ornamentation and used to enclose an indefinite number of paper covered books while the loose leaf data is being attached to the leaves of the several units.

Other objects and uses relating to specific parts of the binder will be brought out in the following description: f

In the drawings:

Figure l is a perspective view of a loose leaf binder book embodying the various features of my invention, the book being open to show the binding lacing for att-aching the several units to the outside cover.

Figure 2 is a perspective view of the back strip and the means for Vattaching one of the multiple sheet units thereto, portions of three sheets of said unit being show!! in Serial No. 535,680.

section and a portion of one of the loose leaf binding strips being also shown as adhesively applied to the uppermost sheet.

Figure 8 is an enlarged sectional View taken on line 3-3, Figure 1 except that the adjacent portions of the main cover is shown in edge elevation.

Figure 4C is an enlarged longitudinal sectional view through the center of the book taken on line 4 4, Figure l.

As illustrated, this binder comprises* a plurality of, in this instance six, multiple sheet units -l-, a binding strip -2-, a flexible cover -3- for receiving the binding strip -2- and the several units attached thereto, and a main outside cover '--flrof stiffer material together with a vsuitable lacing by which all of the foregoing parts may be bound together in book form.

Each multiple leaf unit comprises a binding flap -5-, a tab strip -6 and a plurality of, in this instance three, leaves -7`, all of which parts are preferably made of tough paper or equivalent flexible material.

The main cover -4- is substantially rectangular in plan when unfolded and is provided with parallel lengthwise creases or scores -8- in transversely spaced relation at equal distances from, and at opposite sides of, the longitudinal center to form a main back piece -9- and similar covers 10- foldable along the score lines -8--.

The flexible cover -3- is of slightly less area than that of the main cover 4 and is also scored at -llalong parallel lengthwise lines at equal distances from, and at opposite sides of, the longitudinal center slightly less than the spacing of the scores -8 of the main cover to permit the flexible cover to fold along those lines wholly within the longitudinal edges of the main back piece -9-, thus forming a central back piece -12-, and opposite similar flexible covers -13, said cover -3- resting loosely upon the inner surface of the main cover 4- for easy detachability therefrom when desired but is normally held in operative relation to said main cover by suitable lacing hereinafter described.

The binder strip 2- is of substantially the same length and width as the back piece F12- of the cover -3 and is provided with an adhesive back pasted to the inner Sulface of the back pee 512m for reinforcinglpurposes and also to form a separate,y

Y strip Q and for this purpose, the Vunder Y side thereof is provided with an adhesive pasted to the upper face of the reinforcing strip, and while'in this instance, it extends` under the tab strip the full width thereof to support the same it may be formed integral with the adjacent edge of said tab strip, which latter is provided on its under side with an adhesive pasted to the upper face of the extension Vas 5 so that the flap 5 actually becomes a part of the tab strip and in scored longitudinally along the inner edge of the tab strip to permit the latter to readily fold in opposite directions along the score line as shown in Figure 3.

.Each tab strip is provided with a plurality of tabs M of substantially uniform width and length integrally united to the outer edge of the main body and scored lengthwise along said edge to permit them to readily, fold and unfold but are normally folded upon the main body with their free edges beneath a protecting' strip 15 which in turn is adhesively secured along its inner edge to the main body while its other edge is free and constitutes a relatively narrow flap to overlap upon the foldedV ends of all of the tabs of the corresponding multiple sheet'unit. v- Y The outer faces of these tabs M are provided with an adhesive so that when unfolded, they may be adhesively applied to the inner faces of the adjacent edges of the sheets` 7 for attaching the latter to the tab strip. That is, the outer folded edges of the tabs extend along a straight line parallel with the opposite edge and constitute alining abutments with which the inner edges of the sheets 7 may be alined while attaching one or more of the tabs 14 to each unit intoflat relation one upon the other when the book is open.

In attachingl the several multiple sheetV units to the back piece 2 the adhesive flaps 5 are pasted to the upper face thereof in sequence from right to left so that the score or folding line of the first one at the right will be substantially coincident.

with or slightly inside of the corresponding edge of the back piece 2 the next one being adhesively secured to the back piece in such manner as to allow approximately half the width thereof to overlap upon the first flap to which it is also adhesively secured, the remaining flaps being sequentially secured in similar relation as shown more clearly in Figure l3 in which it will be seen that the folding lines as 6 of the several tab istrips will be in transversely spaced relation and parallel.

The tabs are, of course, flexible and readily bent at'their junctions with the inner edges of the sheets 7 and also along the score lines 14l at their junctions with f the main body of the tab strip, which enables the sheets'to lie flatwise one upon the otlier'when the book is open and permitting the'A matter displayed thereon to also lie flatwise. l

are integrally united tol one edgeV of a mainV body 18 and normally folded under' a,

protective flap 19 the main body 18 being provided withvan `adhesive on its under side which enables it to be pasted in any desired position to either surface of any one of the sheet-s.

The means for attaching the loose sheets Y i That is, Vany number of these loose leaf Y retaining' strips 16 l may besecured to any one sheetpreferably to the inner surface thereof and parallel with the longitudinal center of the book although it is evident that they may be secured cross-wise or Y diagonally if desired and that eachV sheet may have any number of binding strips which may be appliedras required.VV L' Y rlhe baclr piece 9 of 'the'main' cover 4.- and also'the back` piece 12 of the flexible cover 8 together with. the overlying binding strip Q and flaps 5 which may overlie' the longitudinal center of the binding` strip Q are provided with apertures 20 in longitudinally spaced relation for receiving Yalacing member 21 the Vends' j of which are passed through the apertures 20 from the upper side and tied at the back at 22 to detachably secure the flexible cover 3 -with the several multiple ysheet units 1 bound therein to the main cover lt so that when the several leaves are filled with the matter to be filed, the flexible cover with the filled multiple units therein may be removed from' the main cover by simply removing the lacing 21 thus permitting Y the substitution of a new flexible cover with the multiple sheet units bound therein upon the same outer cover ready for receiving additional loose leaf matter to be filed.

1t is evident, however, that the multiple i Y units are bound together in book form and the book open which is a distinct advantage in the convenient and expeditious convey of the loose leaf matter on each sheet and that each loose leaf on any one sheet may be similarly folded and unfolded by reason of the iiexibility of the attaching tabs -17- which also allow the loose leaves to lay flat- Wise on its supporting sheet -7 When the book is open, said tabs -1'7-- serving to hold the loose sheets in operative position when the book is closed.

What I claim is:

l. In a loose leaf binder of the character described, the combination of a binding strip, a series of flaps adhesively secured to the bindinff strip, tab strips hingedly secured to the flaps and each provided with a plurality of tabs along its free edge, and a plurality of series of display sheets, those of each series being adhesively secured to different tabs of the same strip.

2. In a loose leaf binder of the character described, the combination of a binding strip, a series of flaps adhesively secured to the binding` strip, tab strips hingedly secured to the flaps and each provided With a plurality of tabs along its free edge, and a plurality of series of display sheets, those of each series being adhesively secured to diiferent tabs of the same strip, said tabs being hingedly attached to their respective strips and also hingedly attached to their respective sheets to enable the sheets to lie latvvise one upon the other when unfolded.

3. In a loose leaf binder of the character described, the combination of a main cover having a central longitudinal back piece, a supplemental cover havinga central longitudinal back piece registering With that of the first named back piece, a binding strip adhesively secured to the second named back piece, a series of flaps adhesively secured to the binding strip, tab strips hingedly secured tothe flaps and each provided with a plurality of tabs alongits free edge, and a plurality of series of display sheets, those of each series being adhesively secured to diiferent tabs of the same strip, said tabs being hingedly attached to their respective strips and to their respective sheets to enable the sheets to lie flatvvise one upon the other When unfolded.

In Witness whereof I have hereunto set my hand this 8th day of February 1922.
